The amount of actual toxic waste created by a nuclear plant is actually miniscule. I can ask the same question though, why does no one consider the toxic waste of anything? Wind turbines kill thousands of birds. Solar panels leak toxic waste into our groundwater.

The thing about nuclear is you could power everything cheaply.
